ok but has anyone noticed that when john and mary are dancing mary looks sherlock dead in the eyes as she holds john tight to her and sherlock is just there, watching, feeling awkward. this is probably the moment he realises beyond everything else that he quite simply does not belong here, in this room, where everyone has someone to dance with and he, as ever, has no one.
alone is what he has. alone protects him.
except now he knows what it’s like to have someone, so what once protected him is now slowly killing him.
